Bently Nevada Machinery Condition Monitoring
Description
The 2300 Vibration Monitors provide cost-effective
continuous vibration monitoring and protection capabilities
for less critical and spared machinery. They are specifically
designed to continuously monitor and protect essential
medium to low criticality machinery in a wide range of
industries including: oil & gas, power generation, water
treatment, pulp and paper, manufacturing, mining, cement,
and other industries.
The 2300 Vibration Monitors deliver vibration monitoring and
high vibration level alarming. They include two channels of
seismic or proximity measurement inputs from various
accelerometer, Velomitor and Proximitor types, a speed input
channel for time-synchronous measurements, and outputs
for relay contacts. The 2300/20 monitor features a
configurable 4-20 mA output which interfaces more points to
a DCS. The 2300/25 monitor features System 1connectivity for
Trendmaster SPA interface which enables users to leverage
existing DSM SPA infrastructure.
The 2300 Vibration Monitors are designed for use on a broad
range of machine trains or individual casings where the
sensor point count fits the monitor’s channel count and
where advanced signal processing is desired.
